Yiziphi izingxenye zamasethi ejeneretha e-Cummins ezingafanelekile uwoyela wokugcoba?
Sonke siyazi ukuthi isethi evamile ye-Cummins generator inganciphisa ukuguga kwezingxenye futhi yandise impilo yesevisi ngamafutha okugcoba, kodwa empeleni, kunezingxenye ezithile zeyunithi ezingadingi ukugcotshwa ngamafutha okugcoba, futhi ngisho nowoyela wokugcoba uzodlala indima ephikisana nokugqoka , ukuze ezinye izingxenye zesethi ye-generator zingadingi ukugcotshwa ngamafutha? Okulandelayo incazelo emfushane yejeneretha kanjiniyela engu-500KVA Cummins esethwe eNigeria.
Isibonelo isethi yejeneretha ye-cylinder eyomile ye-Cummins, uma i-cylinder liner eyomile igcotshwe ngamafutha okugcoba, i-generator ingase ishise futhi ithinte ukusebenza kwayo okuvamile. Njengoba injini izokhiqiza izinga lokushisa eliphezulu ngesikhathi sokusebenza, isilinda sizokhula lapho sishisa, kodwa i-cylinder block inokwandiswa okuncane ngenxa yokushisa kwamanzi abandayo nokushisa okuphansi. Ingaphandle le-cylinder elomile liseduze nendawo ephezulu yembobo, eyenziwa ekuqhubeni ukushisa. Ingaphandle le-cylinder ligcotshwe nge-lubricant yebhotela, okuvimbela ukuxhumana okuhle phakathi kwezindawo ezimbili.
Ukufaka amafutha okugcoba ekhanda le-cylinder kanye ne-cylinder gasket ukuze uvalwe futhi uqiniswe akufanele ulahlekelwe. Ngemva kokuqinisa ikhanda le-cylinder, leyo ngxenye yamafutha okugcoba izokhanywa ngaphandle kwe-cylinder futhi ichithe, futhi enye ingxenye izofakwa ku-cylinder. Lapho i-generator isebenza, amafutha okugcoba azohwamuka ekushiseni okuphezulu, futhi umkhiqizo utholakala phezulu kwe-cylinder piston. Lapho izinga lokushisa lesethi ye-diesel generator likhuphuka, ungqimba lwamafutha ekhanda le-cylinder, i-cylinder head gasket kanye ne-cylinder block surface izonyamalala, futhi i-cylinder head nut iyaxega, okuholela ekuvuzeni komoya, ukuvuza komoya kanye nomoya omubi oqondile. Kungase futhi kube ngenxa yokushisa okuphezulu nokupheka kwebhotela, okwenza kube nzima ukuqaqa ikhanda le-cylinder kanye ne-cylinder gasket.
Onjiniyela bakwa-Walter bazogcizelela izici ezingenhla ngesikhathi sokuqeqeshwa kokulungisa isethi ye-generator, ukuze kugwenywe amaphutha okunakekela amakhasimende. Uma ungakuqondi okuqukethwe okungenhla, ungaxhumana nonjiniyela wakwa-Walter noma umphathi wezentengiso, futhi ochwepheshe bazokusebenzela ngenhliziyo yonke.
